What should come in place of question mark (?) in the following number series ?
9, 4.5, 4.5, 6.75, 13.5, 33.75, ?
Successive multiples of 0.5 are added
9 + $$0.5 \times 1$$ = 4.5
4.5 + $$0.5 \times 2$$ = 4.5
4.5 + $$0.5 \times 3$$ = 6.75
6.75 + $$0.5 \times 4$$ = 13.5
13.5 + $$0.5 \times 5$$ = 33.75
33.75 + $$0.5 \times 6$$ = 101.25
